How to Code for Creating Validation Rule Challenge?

I understand the concept behind it from this.


But the article does explain what all the coding syntax mean or how to put it together but the challenge asks me to do exactly that...

Did I miss a step? I am stuck but I don't to copy and paste the formula. Where can I learn to write the formula for this challenge from scratch?

I do not know what the AND, OR , NOT, etc. mean in the beginning of the formula expression syntax.
